Set the parameter value for the parameter entry key=locale to the correct language suffix, for example, <entry key="locale" value="ja"/>.

Navigate to MgmtSrvrInstallDir\ADM, and search the enterprise profile (filename entprofile_enterprise_name.xml) for all Application Object Manager references. Make sure their suffixes have the correct language code, for example, change ADMObjMgr_enu to ADMObjMgr_jpn if using the Japanese language.
